This is the Onyx/Challenge "rack" configuration. If memory
serves, it can hold up to three Ebus/VME card cages, and at least one
19" rackmount disk chassis. In my experience, these have been just
about as common as the deskside chassis, though a real pain to move.
The big plus is that they have very good rollers. They do, sadly,
also suffer from the same old SGI problem of cheap plastic skins that
practically disintegrate if not handled like fine china. If you so
much as look at one of those front door hinges wrong, it will break.
